FLANN : Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) for Windows #435
Description
I am actually setting up the Point Cloud Library (PCL). However, it requires a few other dependency libraries, and one among them was FLANN.
So, I wanted to build the FLANN from sources:
- Downloaded the souces from the Git link.
- Created a build directory
- Set CMake SOURCE code path - C:/PCL/flann-master
- Set CMake Build binaries path - C:/PCL/flann-master/build
- Checked the Grouped and Advanced options
- Configure
CMake Warning (dev) at CMakeLists.txt:17 (if):
Policy CMP0054 is not set: Only interpret if() arguments as variables or
keywords when unquoted. Run "cmake --help-policy CMP0054" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.
Quoted variables like "MSVC" will no longer be dereferenced when the policy
is set to NEW. Since the policy is not set the OLD behavior will be used.
This warning is for project developers. Use -Wno-dev to suppress it.

The import takeaway is Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
Using PkgConfig with CMake is not a truly cross-platform solution, as Windows does not come with the pkg-config utility installed.
So any solution for this issue ?
