I get an error while running the CMake configure step in a fresh copy of the repository:

Creating directories for 'simde-populate'
  Performing download step (git clone) for 'simde-populate'
  Cloning into 'simde-src'...
  fatal: reference is not a tree: df63f88a364da6be3963b4924c327b12f88d7748
  CMake Error at simde-subbuild/simde-populate-prefix/tmp/simde-populate-gitclone.cmake:40 (message):
    Failed to checkout tag: 'df63f88a364da6be3963b4924c327b12f88d7748'

Steps to reproduce:

git clone git@github.com:jeremyong/klein.git
cd klein
cmake -B build -S .

Possible fix:

Modifying CMakeLists.txt#L35 from GIT_SHALLOW ON to GIT_SHALLOW OFF solves the issue. I'm not sure if that's the correct approach though.

Does it work if you change that commit hash to v0.7.2? It's possible something changed in the upstream simde branch.

Yes, that also works (with GIT_SHALLOW ON this time):

FetchContent_Declare(
    simde
    GIT_REPOSITORY https://github.com/simd-everywhere/simde
    GIT_TAG v0.7.2
    GIT_SHALLOW ON
)
