Windows 10 : cmake can't build irony server because of relative path

[antonymerle]

Hello,
I fail to build irony server on windows 10 because of relative path... I erased the irony floder to start clean, but it didn't help...

`-- mode: compilation; default-directory: "~/AppData/Local/Temp/build-irony-server-1.4.0/" --
