Compile a gpsd client in C++

I'm attempting to compile a client program of gpsd using the following command:

g++ gpsClient.cpp -o gpsClient $(pkg-config --cflags --libs libgps)

The source code begins like that

#include <libgpsmm>

The error is the following:

Package libgpsmm was not found in the pkg-config search path.

To get data from gpsd, make sure you have installed libgps-dev:

sudo apt install libgps-dev

And in case you want to use it in CMakeLists, gps- and m-linker flags should be linked to the target:

set(GPS_FLAGS m gps)
#
# other components  
# 
add_executable([PROJECT_NAME] ${SOURCE_FILES} ${HEADER_FILES})
target_link_libraries([PROJECT_NAME] ${GPS_FLAGS})

Answering in case someone else encounters this issue.

The proper header file to include is, as suggested in the comments:

#include <libgpsmm.h>

pkg-config should then be able to find the proper search path, assuming gpsd (and/or depending on the OS, libgps-dev or variants thereof) is installed.

There's a good gist on github I use as a base for interacting with gpsd clients in C++ here: example c++ gpsd program using libgpsmm

It even has an example compile command (adapt to clang or other if needed):

g++ -Wall -std=c++17 -pedantic $(pkg-config --cflags --libs libgps) gpsd-example.cpp -o gpsd-example
