Adding 3rd part library (taco) by FetchContent_Declare causes issues - cmake

Question

I would like to add a 3rd party lib (called taco) to my project. In the CMakeLists.txt of my project I did the following:
FetchContent_Declare(
taco
GIT_REPOSITORY https://github.com/tensor-compiler/taco.git
GIT_TAG master
)
FetchContent_MakeAvailable(taco)
When compiling, the compiler complains

If I build this library (taco) without using FetchContent_Declare (mkdir build && cd build && cmake ..), this issue won't show up.
After I fixed this by adding the scope 'taco::ir::' to conjunction, I got the second issue:
/home/miaodi/repo/mfemMechanics/release/_deps/taco-src/tools/taco.cpp:35:10: fatal error: taco/version.h: No such file or directory
35 | #include "taco/version.h"
| ^~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [_deps/taco-build/tools/CMakeFiles/taco-tool.dir/build.make:76: _deps/taco-build/tools/CMakeFiles/taco-tool.dir/taco.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:889: _deps/taco-build/tools/CMakeFiles/taco-tool.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
which also does not happen when I compile it without using FetchContent_Declare.
My question is: how can I fix these issues without touching the source code?
