Trying to compile devel/cmake on Solaris 11.3/sparc with GCC 4.9.4 fails here:

This error boils down to the fact that libuv is not used by cmake on sparc, but only on i86. "bmake configure" shows this on i86:

-- Found LibUV: /opt/pkg-hrz/20170529/lib/libuv.so (found suitable version "1.11.0", minimum required is "1.0.0")

That line is completely missing on sparc, because the relevant test is missing in "CMakeFiles/Makefile.cmake". But now I am lost, I can't pin down the spot where someone decides to not include this test and why. devel/libuv is installed both on i86 and sparc, and the build environment is also identical (one pkgsrc tree, same GCC 4.9.4 on both platforms).
