fatal error: ghc/fs_std.hpp: No such file or directory when compiling my c++ program

[Duddy67]

Hi all,

I'm trying to compile a little c++ program with the sfizz library but I have an error. Firstly, I cloned sfizz in my project and built it:

SFZPlayer/
├── sfizz/               # Cloned sfizz repository
├── Makefile
└── main.cpp

cd sfizz
mkdir build
cd build
cmake ..
make

then I tried to compile my program but I have this error:

sfizz/src/sfizz/Synth.h:13:10: fatal error: ghc/fs_std.hpp: No such file or directory
   13 | #include <ghc/fs_std.hpp>
      |          ^~~~~~~~~~~~~~~~

I create a new directory called ghc and put both the fs_std.hpp and filesystem.hpp files in it. But I'm still having the same error.

Here's my Makefile:

# Compiler
CXX = g++
CXXFLAGS = -I sfizz/src -I sfizz/external -I ghc -std=c++14

# Paths
SFIZZ_PATH = sfizz
LIBS = -lsndfile -lpthread -labsl_strings -labsl_base

# Targets
TARGET = SFZPlayer
SOURCES = main.cpp
OBJECTS = $(SOURCES:.cpp=.o)

# Rules
all: $(TARGET)

$(TARGET): $(OBJECTS)
	$(CXX) -o $@ $^ -L $(SFIZZ_PATH)/build/src -lsfizz $(LIBS)

%.o: %.cpp
	$(CXX) $(CXXFLAGS) -c $< -o $@

clean:
	rm -f $(TARGET) $(OBJECTS)

# Phony targets
.PHONY: all clean

Can someone help me ?
