Hello,
I am trying to create a 'boiler plate' project

for my needs I would like to use mir-optim

However, I cannot seem to get passed compilation errors
when including mir-optim library.

I do not have any problem including mir-cpuid library.
So I am somewhat confused what I might be doing wrong.

Thank you in advance for any help.

Replying to my own question.
I resolved previously reported ldc2 error.
I removed distro (Ubuntu/Mint) version of ldc , and instead 
installed 1.16 from the
release page ( https://github.com/ldc-developers/ldc/releases ).

The compilation error is now gone.
I also created the 'activate' script to setup paths (it was not 
avaialble in the LDC tar)
in case is anyone interested it is attached below (just modify 
LDC2_ROOT variable)
