Hi, I'm trying to use precompiled headers with VS2005. Therefore, I need to set on the target two additional compile flags: /Yu with the header to be precompiled, and /Fp with the path of the resulting PCH. But whatever I try, cmake will only set one of them.
The following will only set the second compile flag. in this case /Fp. If I reverse the lines, it will set /Yu. set_target_properties( ${target} PROPERTIES COMPILE_FLAGS /Yu"${hdrfile}" COMPILE_FLAGS /Fp"${pchpath}" ) If I put both compile flags on one line as following, it is not accepted by CMake as there's an incorrect number of arguments: set_target_properties( ${target} PROPERTIES COMPILE_FLAGS /Yu"${hdrfile}" /Fp"${pchpath}" ) Splitting it into two statements as following, has the same effect (only setting the second one) set_target_properties( ${target} PROPERTIES COMPILE_FLAGS /Yu"${hdrfile}" ) set_target_properties( ${target} PROPERTIES COMPILE_FLAGS /Fp"${pchpath}" ) Using set_property with APPEND, has the effect that it concatenates both flags with a semicolon, something like /Yufoobar.h;/Fpfoobar.pch, so that VS thinks the header to be precompiled is called "foobar.h;/Fpfoobar.pch". Err, wrong =) set_property( TARGET ${target} APPEND PROPERTY COMPILE_FLAGS /Yu"${hdrfile}" /Fp"${pchpath}") It even has this same concatenation effect when I split it into two statements: set_property( TARGET ${target} APPEND PROPERTY COMPILE_FLAGS /Fp"${pchpath}") set_property( TARGET ${target} APPEND PROPERTY COMPILE_FLAGS /Yu"${hdrfile}") And when I leave out the APPEND, we're back to square one where it only sets the second compiler flag: set_property( TARGET ${target} PROPERTY COMPILE_FLAGS /Fp"${pchpath}") set_property( TARGET ${target} PROPERTY COMPILE_FLAGS /Yu"${hdrfile}") So, my question obviously is: what's the proper way to set TWO (or more) additional compiler flags on na target. Thanks in advance, Bram PS: Technically, it's not really necessary to set /Fp, as the default is fine, but it still strikes me as cumbersome. _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
