sccache inconsistency with cl (Fatal error LNK1104: cannot open file) #2485
Description
Stumbled upon LINK : fatal error LNK1104: cannot open file 'main.dir\Debug\main.obj' trying to build visual studio project with cmake and sscache.
Managed to narrow it down to a simple snippet to reproduce.
Basically when compiling main.cpp with output path main.dir\Debug\\, cl outputs file as main.dir\Debug\main.obj.
But sccache cl outputs file as main.dir\Debug.obj.
rmdir /s /q main.dir
:: tree /F
:: CMakeLists.txt
:: main.cpp
mkdir main.dir\Debug
cl /c /Fo"main.dir\Debug\\" main.cpp
tree /F
:: Folder PATH listing for volume L Volume
:: Volume serial number is AACD-E6D9
:: L:.
:: │ CMakeLists.txt
:: │ main.cpp
:: │
:: └───main.dir
:: └───Debug
:: main.obj
rmdir /s /q main.dir
mkdir main.dir\Debug
sccache cl /c /Fo"main.dir\Debug\\" main.cpp
tree /F

// main.cpp
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
