[BUG] devcontainer failing to compile cmake test program

从 devcontainer.json 配置开始，复现报告中所示的初始 CMake 编译器检查。在移除 SCCACHE 环境变量后比较行为；当 devcontainer 能够为没有 sccache 服务器凭据的用户完成配置，或已清楚记录该限制和变通方案时，即视为完成。

I'm planning to suggest a small change around the tbbexec and its base pool.

First I wanted to try out my idea, how it would look like, in the stdexec environment. So, I've loaded the devcontainer but the compiler failed during the first cmake step, when the compiler is checked:

[1/2] /usr/bin/sccache /usr/bin/clang++    -MD -MT CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o -MF CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o.d -o CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o -c /home/coder/stdexec/build/CMakeFiles/CMakeScratch/TryCompile-pUMJrB/testCXXCompiler.cxx
[cmake]     FAILED: CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o 
[cmake]     /usr/bin/sccache /usr/bin/clang++    -MD -MT CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o -MF CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o.d -o CMakeFiles/cmTC_0ee0d.dir/testCXXCompiler.cxx.o -c /home/coder/stdexec/build/CMakeFiles/CMakeScratch/TryCompile-pUMJrB/testCXXCompiler.cxx
[cmake]     sccache: error: Server startup failed: cache storage failed to read: PermissionDenied (permanent) at stat => no valid credential found and anonymous access is not allowed
[cmake]     

The issue is around the sccache usage and authentication. I've found a similar issue with the cccl library. Thus, I've removed the SCCACHE environment variables from the devcontainer.json. It solved the issue.

I wouldn't like to suggest to create a new devcontainer setup for users who has no access to the sccache servers, rather to close this issue as a known issue and with the workarounds, to help others to find a solution.

What do you think? Do you have maybe a better solution for the issue?
