[BUG] No cmake file is generated for LAMMPS, when installing the pre-compiled C library

[xwuupb]

Bug summary

With the pre-compiled C library I installed DeePMD-kit by following the instructions here. Then, I tried to install LAMMPS with CMake (see instructions here). Then, I got the following error message:

CMake Error at /dev/shm/x/deepmd-kit-3.1.0/source/lmp/builtin.cmake:15 (find_package):
  By not providing "FindDeePMD.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "DeePMD", but
  CMake did not find one.

  Could not find a package configuration file provided by "DeePMD" with any
  of the following names:

    DeePMDConfig.cmake
    deepmd-config.cmake

  Add the installation prefix of "DeePMD" to CMAKE_PREFIX_PATH or set
  "DeePMD_DIR" to a directory containing one of the above files.  If "DeePMD"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:1121 (include)

Tested DeePMD-kit versions are 3.1.1 and 3.1.0.

However, if I compile DeePMD-kit from source code, the cmake file is generated for LAMMPS and can be found for compiling LAMMPS.

DeePMD-kit Version

3.1.1 and 3.1.0 are tested

tar xf libdeepmd_c.tar.gz
export path_libdeepmd_c=/dev/shm/x/libdeepmd_c
#
# DeePMD source
#
wget https://github.com/deepmodeling/deepmd-kit/archive/refs/tags/v3.1.1.tar.gz
tar xf v3.1.1.tar.gz
export deepmd_source_dir=/dev/shm/x/deepmd-kit-3.1.1
#
# install
#
cd $deepmd_source_dir/source
mkdir b && cd b
export deepmd_root=/dev/shm/y
cmake -DDEEPMD_C_ROOT=$path_libdeepmd_c -DCMAKE_INSTALL_PREFIX=$deepmd_root ..
make -j 8 && make install
#
# find no cmake file for LAMMPS
#
find $deepmd_root -iname "*cmake*"
