Platform

• [x] Windows
• [ ] macOS
• [ ] Linux

Repro steps:

1. git clone https://github.com/libigl/libigl F:\gitP\libigl\libigl
2. set CL= /permissive-
3. mkdir F:\gitP\libigl\libigl\build_amd64 and cd F:\gitP\libigl\libigl\build_amd64
4. cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DBOOST_ROOT=F:\tools\boost_1_70_0\x64 -DCMAKE_CXX_COMPILER_LAUNCHER=sccache -DCMAKE_BUILD_TYPE=Release -DLIBIGL_USE_STATIC_LIBRARY=ON -DLIBIGL_COPYLEFT_CGAL=ON -DLIBIGL_COPYLEFT_COMISO=OFF -DCMAKE_JOB_POOLS=pool-linking=1;pool-compilation=2 -DCMAKE_JOB_POOL_COMPILE:STRING=pool-compilation -DCMAKE_JOB_POOL_LINK:STRING=pool-linking -S .. 2>&1
5. msbuild /m /p:Platform=x64 /p:Configuration=Release /p:BuildInParallel=true libigl.sln /t:Rebuild 2>&1

Expected result:

build successfully.

Actual result:
