[CMake] Abuse of find_package COMPONENTS, or not?

[Marcel Loose]

Hi Denis,

What do you mean with like FindBoost did? Can you be a bit more
specific? 

Boost components are AFAIK independent of one another, and they're
definitely not mutually exclusive, which is the case in my propsed setup
of FindFFTW?

For example:

  find_package(FFTW COMPONENTS single double)

shoud be flagged as an error, because single and double are mutaully
exclusive.

Best regards,
Marcel Loose.

Hi all,

I am busy writing a FindFFTW macro. Depending on whether you want to use
single or double precision you should include a different header file
and link to a different library. The same is true when using
parallelization like mpi or threads.

Now I was considering to pass these options as COMPONENTS, since, AFAIK,
that's the only way to pass parameters to a FindXXX macro.
So, for example, the user of FindFFTW would do something like:

  find_package(FFTW COMPONENTS single threads)

Do you guys consider this a good or a bad idea? If you think it's a bad
idea, do you have a suggestion how to do things differently?

Best regards,
Marcel Loose.
