Finally, we generate osdef.h using the following function:
function(generate_osdef_h) find_program(BASH_EXECUTABLE bash) execute_process( COMMAND ${BASH_EXECUTABLE} osdef.sh ${CMAKE_CURRENT_BINARY_DIR} WORKING_DIRECTORY ${CMAKE_CURRENT_LIST_DIR} )endfunction()
In order to generate osdef.h in ${CMAKE_CURRENT_BINARY_DIR}/src/auto instead of src/auto, we had to adapt osdef.sh to accept ${CMAKE_CURRENT_BINARY_DIR} as a command line argument.
Inside osdef.sh, we check whether this argument is given:
if [ $# -eq 0 ] then # there are no arguments # assume the target directory is current directory target_directory=$PWD else # target directory is provided as argument target_directory=$1fi
And then, we generate ...
