Issues trying to include with a cmake based project
cpyarger opened this issue · comments
I keep getting unresolved externals issues when trying to build using CMake
here is my current branch,
Any help would be appreciated.
This project is awesome and I can't wait to include it in mine
https://github.com/cpyarger/QMidi/tree/cmake
Here is a copy of my error log

The "Error (active)" are very strange; but the unresolved externals seem mostly to be due to a missing link to the mmsystem library. See what the qmake project files link to.
I did submit a PR tackling CMake support at #23 - you might want to check if this helps with your problem
