cc676c3 OS X: Detect implicit linker framework search paths
2dd67c7 OS X: Detect implicit link directories on modern toolchains
ba58d0c OS X: Link with all framework search paths, not just the last
This means for example, that consumers can use:
target_link_libraries(foo ${QT_QTGUI_LIBRARIES})
instead of also needing to specify all 'public' dependencies:
target_link_libraries(foo ${QT_QTGUI_LIBRARIES} ${QT_QTCORE_LIBRARIES} )
when using the IMPORTED targets. Also populate the
IMPORTED_LINK_DEPENDENT_LIBRARIES property so CMake can help the linker
find shared library dependencies.
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions. Instead we should automatically detect the framework
directories for the active toolchain.
The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories. It displays a block such as:
Framework search paths:
/...
Parse this block to extract the list of framework directories.
Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers. Always treat the paths
<sdk>/Library/Frameworks
<sdk>/System/Library/Frameworks
<sdk>/Network/Library/Frameworks # Older OS X only
/System/Library/Frameworks
as implicit. Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary. Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld". Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.
Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:
Library search paths:
/...
Parse this block to extract the implicit link directories.
While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22). Discard
the non-system link directories added by Xcode. Discard all detected
implicit libraries in the multi-architecture case but keep the
directories. The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.
CONFIGURE_PACKAGE_CONFIG_FILE() now additionally generates
"Any changes to this file will be overwritten by the next CMake run
The input file was FooConfig.cmake.in"
into the configured file.

Handle OpenBSD specific paths in Qt3/Qt4, allowing concurrent building
and installation. Some common programs are renamed with suffixes of
either 3 or 4. Also, allow qt3/qt4 installed under /usr/local to be
searched and recognized appropriately.
6b40e1b VS: Ignore LIBC.lib when linking the CompilerId executables
8e85822 VS: Add the entry point when compiling for WindowsCE
5bf9fd8 VS: Set the correct SubSystem when determinating the CompilerId
This new CPack generator produces an *.msi installer file.
Requires having the WiX Toolset installed in order to work
properly.
Download the WiX Toolset installer "WiX36.exe" here:

This fixes issue #13755.
FPHSA(XX DEFAULT_MSG XX_FOUND)
always succeeded due to the way how the XX_FOUND variable was set.
It was preset to TRUE, and then reset to FALSE if something was missing
(...which had the effect that XX_FOUND itself was already preset when FPHSA
checked whether XX_FOUND is set)
Now XX_FOUND is unset first, and only later on set to TRUE.

332dc09 VS: Add static method to get the base of the registry
d41d4d3 VS: Add CMAKE_VS_PLATFORM_NAME definition to cmMakefile
14861f8 VS: Remove TargetMachine for linker when checking compiler id
Add a dummy mainCRTStartup() function, since the linker searches for
it instead of main() and set the CMAKE_SYSTEM_* variables depending
on the MSVC_C_ARCHITECTURE_ID and CMAKE_VS_WINCE_VERSION variables.
When adding more platforms to the Visual Studio generators a simple
regular expressing can not handle all cases anymore. This new
define holds the name of the Visual Studio target platform.
Modern apps that use multiple threads do NOT want 10 Megabytes of RAM
per thread being used for each thread's stack... Just leave off the
/STACK: argument, and let the compiler use a reasonable default value
for the stack size.
If existing single-threaded apps require the /STACK: argument because
they do need a very large stack size, they can add the flag in their
own CMakeLists files.
If the TargetMachine isn't defined the linker will choose
the correct target depending on the input file. This helps
us later with additional compiler platforms for WinCE.
From the option documentation of VS >= 7.1:
"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires
a fixed-size buffer only to construct precompiled headers. Consequently,
the /Zm compiler option is rarely necessary."
