I installed `GMT.jl` package and installed GMT for 64 bit Windows. Added GMT to PATH also. From Windows command prompt I can run `gmt`, it is showing list of options:
But in Julia, it cannot detect gmt, showing message:
```julia
julia> using GMT
You don't seem to have GMT installed and I don't install it automatically.
You will have to do it yourself.
Download and install the official version at (the '..._win64.exe':
https://github.com/GenericMappingTools/gmt/releases
```
Can anyone please figure out? Is there anything else I need to do to start using `GMT.jl` module?

Ok, my guess is that you made previous attempts to `using GMT` while the GMT itself was not in the path (the NSIS installer software has a dumb bug and is not able to update paths that are longer than 1024 characters or so. Nothing I can do about it) and now it _remembers_ that. Try this
```julia
run(`touch $(pathof(GMT))`)
```
and then start a new Julia session.
FYI, the master version of GMT.jl now tries to automatically install GMT via Conda (on unix) or that same installer on Windows.

@joa-quim Thank you for your response and for this information.
But for me, this line of code did not work. π
Yes indeed, initially when I installed `GMT.jl` package and tried `using GMT`, GMT was not installed and set to the PATH in computer, later I did that. I donβt know where/when exactly I did any wrong!
I removed `GMT.jl` package from Julia and reinstalled. Still Julia cannot detect GMT in computer, showing same message.

That is very strange. If GMT is in the path Julia will find it. The `run(touch..` was only to force a new precompile. What does this print?
```julia
readlines(`gmt --version`)
```

In REPL it prints:
```julia
julia> readlines(`gmt --version`)
1-element Vector{String}:
"6.1.1"
```
And if I run that line of code it throws error as below:
```julia
julia> run(`touch $(pathof(GMT))`)
ERROR: IOError: could not spawn `touch 'C:\Users\...\.julia\packages\GMT\wprG1\src\GMT.jl'`: no such file or directory (ENOENT)
```

Ok, so it found GMT but one need to force a rebuild to update that info in the prebuild cache (that was the intention of the `toutch` command but I forgot that it only works with `dev'd` versions).
Delete all files you find in `.julia/compiled/v1.6/GMT/`. This will force a rebuild.

@joa-quim Thank you so much! It worked actually.
I can load and use `GMT.jl` module now without facing any warning/error. π
