Build failure due to weird cmake generated targets

[gl-yziquel]

I've been building quite a few opencog projects lately. This is the first where the usual mkdir build && cd build && cmake .. && make doesn't work. Here is the output:

minime@virtucon ~/h/c/learn (master)> mkdir build
minime@virtucon ~/h/c/learn (master)> cd build/
minime@virtucon ~/h/c/l/build (master)> ls
minime@virtucon ~/h/c/l/build (master)> cmake ..

Built target COPY_TO_LOAD_PATH_IN_BUILD_DIR_FROM__home_minime_home_cellar_learn_scm

Weird things: 1. it skips finding the cc and c++ compilers. 2. the autogenerated target names are out of whack and not interpolated.
