Sure you can:
INCLUDE (MSVC_Compiler_Stuff.cmake)
#----------MSVC_Compiler_Stuff.cmake
if (MSVC)
endif (MSVC)
I do this all the time for OS X specific stuff.
For Linux you can try:
IF(CMAKE_SYSTEM MATCHES "Linux-([3-9]\\.[0-9]|2\\.[4-9])\\.")
# Linux Specific flags
ENDIF(CMAKE_SYSTEM MATCHES "Linux-([3-9]\\.[0-9]|2\\.[4-9])\\.")
if you are using ICC on linux you can also test for that:
IF( ${CMAKE_C_COMPILER} MATCHES "icc" )
SET(CMAKE_EXE_LINKER_FLAGS ${CMAKE_EXE_LINKER_FLAGS} -static-intel)
ENDIF( ${CMAKE_C_COMPILER} MATCHES "icc" )
or test for GCC:
IF(CMAKE_COMPILER_IS_GNUCC)
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fmessage-length=0")
ENDIF(CMAKE_COMPILER_IS_GNUCC)
IF(CMAKE_COMPILER_IS_GNUCXX)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fmessage-length=0")
ENDIF(CMAKE_COMPILER_IS_GNUCXX)
Hope that helps a bit

Unfortunately I cannot simply add one file with platform specifics
for each additional platform. Instead I have to clutter up the main
CMakeLists.txt with if statements.
Especially there is no way to support platforms for which no
explicitly testable variable is available e.g. Linux.
Strange enough is, that WIN32 is set before the PROJECT statement,
while CMAKE_SYSTEM_NAME is not.

Hi all,
I am trying to set the CMAKE_CXX_FLAGS or CMAKE_CXX_FLAGS_INIT
variable, such that it contains flags to turn off specific
warnings for the Visual Studio compiler. I definitely want to set
these additional flags from within a CMakeFile, specifying them
on the command line or interactively is not an option.
I have included a Windows-specific file by using
INCLUDE (${CMAKE_SYSTEM_NAME}.cmake)
The file Windows.cmake contains the line
SET (ENV{CXXFLAGS} "/wd4251")
However this only works after the PROJECT line within the
CMakeFile, because before it CMAKE_SYSTEM_NAME seems to be unset.
On the other hand, when writing the include statement after the
project command, the CMAKE_CXX_FLAGS seem already to be set. If
possible I would like to specify those flags as initial values,
avoiding to use the force option of the set command.
What is the recommended way to add platform-specific compiler
flags from within CMakeFiles?
Any help would be appreciated.
Martin
