find_package(fastrtps) takes too long

[burak-yildizoz]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

Variables should be cached after the first call. Consequent calls to find_package should be done in milliseconds.

Current behavior

Each call takes ~1.3 sec to complete.

Steps to reproduce

cmake_minimum_required(VERSION 3.5)
project(test)

foreach(iter RANGE 10)
    message(STATUS "iter: ${iter}")
    find_package(fastcdr REQUIRED)
    find_package(fastrtps REQUIRED)
endforeach()

Configure with the following command:

cmake -G "Ninja" -D CMAKE_BUILD_TYPE=Release .. --profiling-format=google-trace --profiling-output=perfcmake.json

Wall duration	First call	After then
fastcdr	636 ms	~6 ms
fastrtps	2.84 sec	~1.35 sec
