Compilation error with benchmark.h (after installing google-benchmark)

[MedericFourmy]

Hello, have a compiling issue with benchmark.h I think. I followed issue #918 and installed google-benchmark following the github explanations but now I have the following compilation error:

/usr/local/include/benchmark/benchmark.h: In instantiation of ‘benchmark::RegisterBenchmark(const 
char*, Lambda&&, Args&& ...)::<lambda(benchmark::State&)> [with Lambda = void (&) 
(benchmark::State&, std::__cxx11::basic_string<char>); Args = {std::__cxx11::basic_string<char, 
std::char_traits<char>, std::allocator<char> >&}]’:

                                     ^

Is my installation of google-benchmark faulty?

@MedericFourmy I also have the same problem. What version do you try to build?

In my environment, success to build spdlog using v1.2.1 tag.

$ git checkout v1.2.1
Previous HEAD position was 4003218 Merge branch 'v1.x' of https://github.com/gabime/spdlog into v1.x
HEAD is now at 10e809c Merge pull request #864 from DimRochette/v1.x

$ cmake..

$ make -j2
