Hi,
For header files, that's quite a normal thing to do - you just need to add the
CMAKE_CURRENT_BINARY_DIR to your include directories.
For .cpp files, you can write your target so that it is referencing the source
file in the binary directory. I.e.:
configure_file(
${CMAKE_CURRENT_SOURCE_DIRECTORY}/file1.cpp.in
${CMAKE_CURRENT_BINARY_DIRECTORY}/file1.cpp COPYONLY)
add_executable( target1 ${CMAKE_CURRENT_BINARY_DIRECTORY}/file1.cpp)
Is that sufficient for your needs?
If you rather need a real wildcard way to override arbitrary source files,
then you're probably out of luck. You could still write a wrapper around
add_executable and add_library that inspects source directory and binary
directory, but that might not be worth the effort...
