cmake error

[dansass]

when i wnat to run cmake .. && make it says

CMake Error: The source directory "/home/pi" does not appear to contain CMakeLists.txt.

and i am in the skymax-demo directory

whats going on?

[manio]

You are not in skymax-demo directory :)

[dansass]

I think I am

[manio]

you're right just type cmake (without ..) and see if it helps

[dansass]

Still no luck :( here are my commands that i ran

[manio]

what if you do:

clone [...]
cd skymax-demo
mkdir build
cd build
cmake ..
make

[dansass]

for kicks i tried;

Im wondering if i Maybe installed cmake wrong. It sure is acting weird

[manio]

Yeah, you probably have something wrong. Try to clone to some other dir then your home dir, like /tmp For me it is working no matter if i do "cmake . " in main dir, or "cmake .." in build subdir:

/tmp/skymax-demo/build/ cmake ..

Hello,

thanks for the awesome software work :dancing_women:

please update build instructions: like this:

# -1) tested on 
hostnamectrl; # Debian GNU/Linux 11 (bullseye)

# 0) have cmake installed
apt update; apt install cmake;

# 0.1) version installed
cmake --version
cmake version 3.18.4
CMake suite maintained and supported by Kitware (kitware.com/cmake).

# 1) use https instead of ssh
git clone https://github.com/manio/skymax-demo.git

# 2) go into newly created subdir
cd skymax-demo

# 3) prepare build
cmake .

# output ought to be:

-- The C compiler identification is GNU 10.2.1
-- The CXX compiler identification is GNU 10.2.1

# 4) build
