MSVC - cannot cache with "@" (command files) #1183
Description
Hi,
I've been trying out sccache for an MSVC based project with a custom build system that uses command files for all the arguments, but it seems that sccache doesn't cache any call that uses the @ syntax. After running my test project, this is the output from sccache.
sccache -s

The format of every one of the compile calls is:
sccache "C:\BuildTools\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64\cl.exe" @..\build\Win64\foo.cpp.command
Is there any planned support for command files in MSVC?
