Hi
I'm writting a FindGTK+.cmake module which should set the CFLAGS and LDFLAGS requiered by GTK+ using pkg-config.
I have:...IF(NOT __FIND_GTK_FOUND) MESSAGE( "-- GTK+ version ${__FIND_GTK_VERSION_FOUND} found" ) SET(FIND_GTK_FOUND TRUE)
EXECUTE_PROCESS(COMMAND ${__FIND_GTK_PKG_CONFIG} --cflags ${__FIND_GTK_STRING} COMMAND xargs printf %s\ OUTPUT_VARIABLE FIND_GTK_CFLAGS )
EXECUTE_PROCESS(COMMAND ${__FIND_GTK_PKG_CONFIG} --libs ${__FIND_GTK_STRING} COMMAND xargs printf %s\ OUTPUT_VARIABLE FIND_GTK_LDFLAGS )
ENDIF(NOT __FIND_GTK_FOUND)
where __FIND_GTK_FOUND is the the exit status of pkg-config --atleast-version=... --modversion gtk+[-2.0]
The problem is the EXECUTE_PROCESS. If I only writeEXECUTE_PROCESS(COMMAND ${__FIND_GTK_PKG_CONFIG} --cflags ${__FIND_GTK_STRING} OUTPUT_VARIABLE FIND_GTK_CFLAGS)
then FIND_GTK_CFLAGS will have a new-line (\n) character at the end of the string. This is a problem sinceSET_SOURCE_FILES_PROPERTIES(containers.c COMPILE_FLAGS ${FIND_GTK_CFLAGS}) leads to an incorrect Makefile. Why on earthis there a new-line character after all and how can I get rid of it?
EXECUTE_PROCESS(COMMAND ${__FIND_GTK_PKG_CONFIG} --cflags ${__FIND_GTK_STRING} COMMAND sed -n 1p
doesn't work, I don't know why, I still get two lines. The only way I could get rid of the new-line is with the"xargs printf %s\ " command, but I don't like this very much.
How can I solve this problem? Is this pkg-config problem after all?
RegardsPablo
