Cmake build helper + Intel Fortran

[kylemacfarlan]

This is similar to #2747, but there isn't as elegant a workaround, so I thought it was worth opening an issue.

Intel fortran doesn't understand the verbosity command, and it causes the build to fail.
The workaround I came up with is this:

    cmake = CMake(self, parallel=False)
    command_line = cmake.command_line
    command_line.replace("/verbosity:%s" % cmake.msbuild_verbosity, "", 1)
    self.run('cmake "%s" %s' % (self.source_folder, command_line))
    self.run('cmake --build . %s' % cmake.build_config)`

Unlike #2747, no value that I pass to the msbuild_verbosity argument in the CMake constructor will prevent the command from being issued. It would be nice if there was some way to just remove the "/verbosity: ... " command from being issued at all.

Let's try to fix it for the next release.

Fixed, now CMake(...., msbuild_verbosity=None) will completely remove the flag.

Will be released next Conan 1.16, thanks for reporting.
