Hi,
I'm trying to facilitate compiling the same source file once with a
STATIC_BUILD preprocessor statement defined to 1 and once with it
defined to 0. I can't seem to figure out a way to do this, however.
It appears that the only options I have which are ADD_DEFINITIONS and
SET_SOURCE_FILES_PROPERTIES are gathered together and
processed at the end of the file and are not interpreted atomically
during an ADD_EXECUTABLE() call like I believe they should.
==========
Example 1: This fails because whichever calls
SET_SOURCE_FILES_PROPERTIES last will win.
IF(STATIC_BUILD)
SET_SOURCE_FILES_PROPERTIES(foo.cc
PROPERTIES COMPILE_FLAGS "-DSTATIC_BUILD=1")
ADD_EXECUTABLE(foo-static foo.cc)
ELSE()
SET_SOURCE_FILES_PROPERTIES(foo.cc
PROPERTIES COMPILE_FLAGS "")
ADD_EXECUTABLE(foo-shared foo.cc)
ENDIF()
==========
Example 2: I can't do this either as the compiler simply appends
-DSTATIC_BUILD=1 -DSTATIC_BUILD=0 for both builds
IF(STATIC_BUILD)
ADD_DEFINITIONS(-DSTATIC_BUILD=1)
ADD_EXECUTABLE(foo-static foo.cc)
ELSE()
ADD_DEFINITIONS(-DSTATIC_BUILD=0)
ADD_EXECUTABLE(foo-shared foo.cc)
ENDIF()
I'm running CMake 2.4.6. Any advice would be appreciated. Aside from
forking the source file I'm out of ideas.
