pcl/pcl_config.h: No such file or directory

问题

My environment is below.
・Operating System and version:windows 10 64bit
・Compiler:C:\msys64\mingw64\bin\g++.exe
・PCL Version:1.9.1

pcl_config.h not found as below error occurred when compiled under above env..
Certainly this header file is not included.
Let me know how to solve it.

PS C:\pcl\pcl\examples\common> g++ -o minmax -I ../../io/include -I ../../common/include .\example_get_max_min_coordinates.cpp
In file included from ../../common/include/pcl/PCLHeader.h:10,

Short answer

pcl_config.h is generated via pcl_config.h.in by the cmake tool. So it seems that compilation did not finish correctly.

Longer answer

Please make sure you have compiled the relevant modules of PCL (at least pcl-core) before proceeding
You might prefer a pre-built installation from releases or distributed by a package/source manager of your choice
PCL makes heavy use of other libraries and it is best to supply the dependencies (as mentioned below) via CMake or manually via the -I and -l options. If you provide the location of pcl_config.h, the compiler will complain about Eigen next.

The build instructions are available here. TL;DR: After satisfying the dependencies (cmake, c++ compiler, boost, eigen, flann, vtk and other depending on use-case), run the following commands

cd $PCL_SOURCE_DIR
mkdir -p build; cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j8

Feel free to use any build generator (like Ninja) or change build type to Debug or RelWithDebInfo as per your needs.
