CMake generation error with fusesoc

[mkurc-ant]

When running make env from the root directory everything passes fine. Later if any of CMake scripts gets modified and a command make <target> is invoked CMake tires to re-generate related Makefiles. Then the error emerges:

This is a result of not being the conda environment. "make enter" can be used to use the right env.
