data path not relocateable

[maxnbk]

in acesrender.cpp, the illuminant and camera data path defaults to "/usr/local/include/rawtoaces/data/illuminant", but a build which uses a CMAKE_INSTALL_PREFIX to be installed elsewhere will not have data there. The default path for the data files should be parameterized by the passed CMAKE_INSTALL_PREFIX if present.

Hi,

Which OS did you install it on?

you can also use the environment variable of "AMPAS_DATA_PATH" to set up the path to the data.

Thanks!

So using AMPAS_DATA_PATH works.
Basically same issue as this issue, because the other two env vars have no effect, but data path works for both purposes.

setting AMPAS_DATA_PATH does not work for the cmf and training data.

These are still hardcoded to:

#define FILEPATH ("/usr/local/include/rawtoaces/data/")

Would it be possible to allow these to use AMPAS_DATA_PATH or their own unique env var?
