Gregor Jasny 93ac2a78d5 Xcode: Obey SYSTEM keyword for includes (#15687)
CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.

As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.

Daniel Pfeifer 7a649111cd Use string(APPEND) in Tests
Automate with:

find Tests -type f -print0 | xargs -0 perl -i -0pe \
's/set\(([a-zA-Z0-9_]+)(\s+)"\$\{\1\}([^"])/string(APPEND \1\2"\3/g'

Brad King c13408279f Add a variable to specify language-wide system include directories
Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.

Brad King ab65862417 Clang: Add separate "AppleClang" compiler id
Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang.  Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION.  Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.

Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.

Stephen Kelly eef6df5c7d Fix OLD behavior of CMP0021.
Exclude Ninja and Xcode from the CMP0021 test

They do not behave the same as the makefile generator with
relative paths.

Don't overwrite the header file for in-source builds.

Stephen Kelly 9cf3547e1c Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property.
Unlike other target properties, this does not have a corresponding
non-INTERFACE variant.

This allows propagation of system attribute on include directories
from link dependents.

Stephen Kelly 2f84dfec93 include_directories: Fix handling of empty or space-only entries
This is a regression introduced in commit 0d46e9a0 (Store includes
from the same include_directories call together., 2013-01-20).

Stephen Kelly 5a5e0fa9d3 Fix clearing of the INCLUDE_DIRECTORIES DIRECTORY property.
This was broken by commit 18a3195a (Keep track of INCLUDE_DIRECTORIES
as a vector of structs., 2012-11-19).

Stephen Kelly 9106b564ae Extract and use the INCLUDE_DIRECTORIES target properties.
Eliminate callers of cmMakefile::GetIncludeDirectories.

All callers of GetIncludeDirectories should go through the local generator
object.

Only the local generator calls cmTarget::GetIncludeDirectories directly.

Bill Hoffman 27aa446352 One more try. Use full path by default, and relative on broken compilers. 2011-06-03 16:16:50 -04:00
Bill Hoffman 2dfc121b89 Use bin tree for inclues to avoid -I with spaces in the path. 2011-06-03 15:05:28 -04:00
Bill Hoffman 6d29b4bfe6 Append and do not clobber CMAKE_CXX_FLAGS in the test. 2011-06-03 13:00:05 -04:00
Bill Hoffman 7815e90e21 Fix for bug#10798. VS10 did not append -I flags with COMPILE_FLAGS prop.
This fix adds a test for this case for all generators.
