[CMake] Exclude CMakeFiles path from GLOB_RECURSE
Hi,
I'm currently trying to use the following line to include all source files into
my build:
file (GLOB_RECURSE Files_CPP *.cpp)
add_executable(test
${Files_CPP}
)
Everything runs fine while using an out-of-source build, but for in-source
builds these lines include .cpp files from the CMakeFiles directory. Is there
any way to exclude this directory within the file command?
Best regards,
Andreas

1. Never use GLOB_RECURSE. It's evil. E.g. if you add or remove source files,
CMake has no way of knowing that it should be re-run. Just list all the files
in your CMakeLists.txt (or, if you think the list is excessively long, create a
file called e.g. files.cmake, put the list in there and INCLUDE it in the
CMakeLists.txt file.
2. Never do in-source builds. CMake creates many, many files, and you don't
want to delete them all individually for a clean build. And there's no way to
implement a safe make clean (e.g. your build system might be running a custom
utility which generates files CMake knows nothing about).

Hi, thanks for your reply. 1. Never use GLOB_RECURSE. It's evil. E.g. if you add or remove source files, CMake has no way of knowing that it should be re-run. I have tested rerunning cmake manually and it worked out well. (Testcase: I added a new .cpp file to the build) I either have to change the CMakeLists.txt or to rerun cmake manually. Seems to be the same effort for me. 2. Never do in-source builds. CMake creates many, many files, and you don't want to delete them all individually for a clean build. And there's no way to implement a safe make clean (e.g. your build system might be running a custom utility which generates files CMake knows nothing about). I know these problems. I will never do an in-source-build again :-) But unfortunately, I have to support in-source builds, too.

Thing is: will you never forget? And it prevents stray files from being picked
up (as you experienced). Also, you get an immediate response if a file is
missing, and not just when the compiler complains about a missing header or you
get undefined references during the linking stage.
If you insist on using GLOB_RECURSE, don't apply it to
CMAKE_CURRENT_SOURCE_DIR, but use GLOB on the CMAKE_CURRENT_SOURCE_DIR and use
GLOB_RECURSE on all the subdirectories individually, so you don't get
CMake-generated stuff.
Also, you could filter out all the items contained in the CMakeFiles directory:
file(GLOB_RECURSE SRCS RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} *.cpp *.h)
string(REGEX REPLACE CMakeFiles/[^;]+;? SRCS ${SRCS})

Ok, that sounds reasoble. (This should especially convince some lazy people :-D ) Thanks a lot! _ http://redirect.gimas.net/?n=M1007xHM2 Räumen Sie Ihr Postfach auf - ganz einfach mit Hotmail!___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
