Summary: pkg_check_modules produces output incompatible with
other cmake variables
Description:
Using pkg_check_modules outputs XXX_LDFLAGS as a list (semi-colon delimited)
whereas CMAKE_EXE_LINKER_FLAGS requires a flat space-delimited string.
Steps to Reproduce:
Run this code on Ubuntu 11.04:
# setup glib2
pkg_check_modules(GLIB2 REQUIRED glib-2.0)
message("GLIB2_LDFLAGS= ${GLIB2_LDFLAGS}")
add_definitions(${GLIB2_CFLAGS} ${GLIB2_CFLAGS_OTHER})
set( CMAKE_EXE_LINKER_FLAGS ${GLIB2_LDFLAGS})
This will output:
GLIB2_LDFLAGS= -L/usr/lib/i386-linux-gnu;-lglib-2.0
which when put into CMAKE_EXE_LINKER_FLAGS, will create invalid flags for gcc--
it will literally emit "-L/usr/lib/i386-linux-gnu;-lglib-2.0" to the
command-line.
Additional Information:
It's unclear how pkg_check_modules is intended to be used-- are we supposed to
write custom code transform its output? Why?
