[Solved] Errors compiling darktable

[starsc]

Hello, I tried to install Sourcery darktable checking with various dependencies (missing cmake in the list but I just discovered), but I'm stuck with this error:

make [2]: *** No rule to generate the target "/ usr/lib64/libGL.so" necessary to "src / dtview / darktable-viewer." Stop.
make [2]: Leaving directory `/ usr/src/slapt-src/graphics/darktable/darktable-0.9/build '
make [1]: *** [src / dtview / CMakeFiles / darktable-viewer.dir / all] Error 2
make [1]: Leaving directory `/ usr/src/slapt-src/graphics/darktable/darktable-0.9/build '
make: *** [all] Error 2
fakeroot - sh darktable.SlackBuild Failed

What do you think?
The dependencies are all ..

[starsc]

Ok, I solved, it was missing a link to libGL.so.1.2
I re-installed mesa and everything compiled well
