Do you know how to solve this problem? Thank you very much.

Can you try to first build FLANN and then install the library?

cd libs/flann
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=<path you want to install flann & pyflann library> ..
make -j8
make install

I have finished
"cd libs/flann
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=<path you
want to install flann & pyflann library> ..
make -j8"
this four step.
and make problem when I run
"make install".

Did you run cmake install or make install?
