__LIB_LIGHTGBM_FILENAME fix

[montanalow]

__LIB_LIGHTGBM_FILENAME doesn't exist BUILD_STATIC_LIB is true, so this custom command should be skipped.

Thanks for your interest in LightGBM, but I don't understand this patch.

Can you please provide a description including:

• the version / commit hash of LightGBM you're building against
• the exact commands you ran
• logs (including the error message) showing the output you got
• details about your environment (operating system? compiler?)

The code you're editing is already inside a block that will not run if BUILD_STATIC_LIB=ON:

LightGBM/CMakeLists.txt

Line 664 in e0c34e7

if(APPLE AND USE_OPENMP AND NOT BUILD_STATIC_LIB)

I strongly suspect that you might be building from a version of LightGBM that does not contain this fix: #6600

Thanks for pointing out the existing patch/fix. I was indeed building with a version (v4.5.0) that did not include it. I'll move my dependency to the master branch until a new release includes that check.
