Encountering Error During CMake Execution

[RenQiuhan]

I encountered an error while executing the command cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=. ... My cmake version is 3.28.0, and gcc version 7.3. The error message I received is as follows:

-- The CXX compiler identification is GNU 7.3.0
-- The C compiler identification is GNU 7.3.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
-- Check for working CXX compiler: /home/anaconda3/envs/AlphaFlow/bin/c++
-- Check for working CXX compiler: /home/anaconda3/envs/AlphaFlow/bin/c++ - broken
CMake Error at /usr/local/share/cmake-3.28/Modules/CMakeTestCXXCompiler.cmake:60 (message):
The C++ compiler

It fails with the following output:

Seems like something is wrong with the installed compilers within this conda environment.

You should be able to install the compilers conda meta package which should contain everything to compile mmseqs
