CMake execution time of one of my projects jumps from 0m6.121s

Most time seems to be spend after "-- Configuring done".
Please "git bisect" the problem.
Thanks, I found these two commits:

Stephen is already looking into it.
Problem seems to show with large numbers of source files e.g.:
cmake_minimum_required(VERSION 2.8.12)
foreach(INDEX RANGE 2000)
set(SOURCE_FILE ${CMAKE_CURRENT_BINARY_DIR}/test_${INDEX}.cpp)
set_property(SOURCE ${SOURCE_FILE} PROPERTY GENERATED ON)
list(APPEND SOURCE_FILES ${SOURCE_FILE})
file(GENERATE OUTPUT ${SOURCE_FILE} CONTENT "void foobar_${INDEX}(){}")
endforeach()
add_library(foobar ${SOURCE_FILES})
