error : undefined reference to symbol 'sem_getvalue@@GLIBC_2.2.5

Ok, but then :
Could not create fragment shader: 0:130(32): error: RHS of `&&' must be scalar boolean

[3dickulus]

look for the boolean test that uses "&&"
check the values being compared at line 130 ?

can't offer much more than that without seeing it, if can you attach the frag file you are using I might be able to offer a  fix

for the sake of the topic, I have adjusted the CMakeLists.txt as quaz0r pointed out, and removed the dependence (MinGW version) on zlib.dll for the windows executables (v1.0.12 available on my website) this patch also brings the ability to populate the EXR alpha channel with data from the DE as described here http://www.fractalforums.com/index.php?topic=21759.msg87183#msg87183 it doesn't have to be depth value, it can be any single float value.
