This adds a test that uses two project commands in the same CMakeLists.txt
file. It also adds a fix so that cmake --build will work in that case.
The fix sets the name of the last project command in the top level
CMakeLists.txt in the cache variable CMAKE_PROJECT_NAME. This variable
is used by cmake --build to find the project name.
Now also CMAKE_ASM_INCLUDE_PATH is written into
CMakeDirectoryInformation.cmake, which is necessary to make
the dependency scanning for included files work.

Fix a crash which occurs when SystemTools::GetPath attempts to process
an empty environment variable.

QKeySequence::Quit does not work on all platforms, and since it
translates to Ctrl+Q on all platforms where it does work, Ctrl+Q was
hardcoded instead.
Fix the regex meant to match errors of the form:
C:\some\dir\source.cpp(17): catastrophic error: could not open source file "some_header.h"
to make the space between ')' and ':' optional.
Since commit 38aab379 (Set CMAKE_<lang>_COMPILER_ID for VS generators,
2011-09-02) the VS IDE generators set the C and C++ compiler id to MSVC
and the Fortran compiler id to Intel. This caused the Fortran test to
fail compatible compiler detection because the if() test
"${CMAKE_C_COMPILER_ID}" MATCHES "MSVC"
is evaluated as the "var MATCHES regex" signature which evaluates the
compiler id "MSVC" as a variable which is defined to 1 which does not
match "MSVC".
Combine tests for non-identical but compatible compiler vendors into a
single regex match whose left hand side will not be defined as a
variable.
The default OS X 10.4 linker incorrectly searches for dependencies of
linked shared libraries only under the -isysroot location. It fails to
find dependencies of linked shared libraries in cases such as the
ExportImport test. It produces errors like:
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning can't open dynamic library:
libtestLib3Imp.dylib
referenced from: /.../ExportImport/Root/lib/libtestLib3lib.1.2.dylib
(checking for undefined symbols may be affected) (No such file or directory, errno = 2)
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols: _testLib3Imp
referenced from libtestLib3lib expected to be defined in
libtestLib3Imp.dylib
or with CMAKE_SKIP_RPATH off to enable install_name in the Export side:
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning can't open dynamic library:
/Developer/SDKs/MacOSX10.4u.sdk/.../ExportImport/Export/impl/libtestLib3Imp.dylib
referenced from: /.../ExportImport/Export/libtestLib3lib.1.2.dylib
(checking for undefined symbols may be affected) (No such file or directory, errno = 2)
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:_testLib3Imp
referenced from libtestLib3lib expected to be defined in
/.../ExportImport/Export/impl/libtestLib3Imp.dylib
Note how "/Developer/SDKs/MacOSX10.4u.sdk" is prepended to the dependent
library path.
Commit 2cff26fa (Support linking to shared libs with dependent libs,
2008-01-31) and commit 82fcaebe (Pass dependent library search path to
linker on some platforms, 2008-02-01) worked around the problem by
defining platform variable CMAKE_LINK_DEPENDENT_LIBRARY_FILES. It tells
CMake to link to dependent libraries explicitly by their path thus
telling the linker where to find them.
Unfortunately the workaround had the side effect of linking dependent
libraries and defeats most benefits of LINK_INTERFACE_LIBRARIES.
Fortunately OS X 10.5 and above do not need to find transitive
dependencies at all so we can avoid the workaround on Modern OS X.
In cmComputeLinkDepends we compute the transitive closure of private
shared library dependencies. When a shared library is added to this
closure we must follow all of its dependencies whether they are private
or public. Previously we only followed the private dependencies. Fix
the implementation to follow the public dependencies too. Also extend
the ExportImport test to cover this case.
