Handle build strategy #2 automatically in cmake

[shadowwalkersb]

This aims to simplify the process of installing from source. The install destination is within a conda environment. That could be the default root environment or any environment that is added and activated by the user. It is possible to enable/disable this behavior by setting/unsetting ENABLE_CONDA cmake variable. It is ON by default.

How does it detect where the conda environment is?

How does it detect where the conda environment is?

Seraches for conda in directories listed in PATH. conda will be in $CONDA_PREFIX/bin. So, the conda environment is the parent directory.

find_path(CONDA_PREFIX conda
                PATHS ENV PATH
               )
get_filename_component(CONDA_PREFIX ${CONDA_PREFIX}/.. ABSOLUTE)

So if you have conda in your path such that 'python' is the conda python, it will find and use it? I guess it will say that you should add conda to your path before running ccmake in the instructions?

The dependencies need to be installed with conda anyways. So, conda will have to be in PATH before getting to cmake step. Instructions are worked on here, http://blake.bcm.edu/emanwiki/EMAN2/COMPILE_EMAN2_ANACONDA.

Once a conda environment is found, it should find all the dependencies, not only python, within that environment.

[shadowwalkersb]

Should we include this in the release?

[sludtke42]

Sure, go ahead, but after you merge, we should do some testing. Are the instructions for using this mechanism for a source compile ready?

Hi I looked up instructions mentioned in the other email. They do not describe openmpi installation. Regards, Pawel
