Compilation issues on Linux/CMake with Musescore 2.1 zip archive

I encountered several compilation issues for Musescore 2.1 zip archive on Linux Fedore 25 using cmake.

I am trying to make a more recent RPM package on Fedora copr.

I tested my build and it looks ok.

Setup:

• compilation was performed in a build directory
• LAM was disabled (as in Fedora spec)
• prefix is /usr/local
• other options as default

0) make or cmake ???

Manual don't mention cmake but make. Why ???

1) Issue when lame is off in ccmake: we have to clear LAME_XXX variables else it complains these variables are unset.

2) all.h

> Man pages have been compressed ready for installation.
> Creating symlink alias for man pages.
> Symlink alias: musescore.1.gz -> mscore.1.gz

> Makefile:151: recipe for target 'all' failed
> make: *** [all] Error 2

I copied manually all.h from source to continue

3) Then g++ complains about -fPIC due to Qt setup

(unfortunately I lost the error message)

I added it to compile all.h

> /usr/lib64/ccache/c++ -fPIC -x c++-header -g -I/usr/include/qt5/ ... -o all.h.gch all.h

4) MP3 code issue (LAM is disabled)

I fixed theses 2 methods
- void UploadScoreDialog::showOrHideUploadAudio()
- void LoginManager::onGetMediaUrlRequestReady(QByteArray ba)

5) At install

These files are not generated ???
