Thanks for the answer, but... [EMAIL PROTECTED]:~/src/wengophone-2.1$ dpkg -l "libasound*-dev" <snip> ii libasound2-dev 1.0.10-2ubuntu4 ALSA library development files [EMAIL PROTECTED]:~/src/wengophone-2.1$ dpkg -L libasound2-dev <snip> ... /usr/include/alsa/asoundlib.h ... <snip> ... /usr/lib/libasound.a /usr/lib/libasound.la /usr/lib/pkgconfig /usr/lib/pkgconfig/alsa.pc /usr/share/doc/libasound2-dev /usr/lib/libasound.so So everything's installed fine. If I run find_package(alsa) it's found fine. But FindAlsa.cmake doesn't set alsa_INCLUDE_DIR or alsa_INCLUDE_DIRS. And in any case, FindAlsa.cmake doesn't get run before we call ow_use_private_libraries(alsa). I have attached a patch I used to work around the problem - it calls PKGCONFIG for alsa, which sets alsa_INCLUDE_DIR, and the compile goes fine. There may be a better way to fix this - I'm open to suggestions. This shows one of the problems of using owbuild, though - it seems like there are only 4 or 5 people who can start answering questions like these - I spent a couple of hours tracking down this problem. By using owbuild macros, rather than standard cmake, we're reducing the number of people who can help when we have a problem, and increasing the learning curve for new people coming into the project. Is there any example of a cmakefile using standard cmake and owbuild so that I can compare the benefits that the owbuild macros bring?
