Multiple E1083 on opencv-master compilation despite the correctness of path and rights

edit

I'm compiling opencv (master) in Windows 10 x64 with VS2017, toolset v141. VS projects are generated by cmake.

I'm having multiple errors such as:

c1xx : fatal error C1083: Cannot open source file: 'I:\opencv-master\opencv\3rdparty\openexr\IlmThread\IlmThreadWin32.cpp': No such file or directory [I:\opencv-master\build\3rdparty\openexr\IlmImf.vcxproj]

However, I don't understand how this could happen since:

the path is an absolute path,
the files do exist,
the right in read access are correct

I'm having this problem only with openexr project.
