Hello,

Apologies if this is silly/misplaced/misguided.

I'd like a way to automate decrypting (via gpg) a file, installing the
decrypted form and removing the temporary decrypted file from the
cmake dir.

I have tried:
<code>
MACRO(ETC_WPA_INSTALL src)
   EXEC_PROGRAM(gpg
               ARGS        -o ${src} -d "${src}.encrypted"
               )
   INSTALL(FILES           ${src}
           DESTINATION     /etc/wpa_supplicant
           PERMISSIONS     OWNER_READ OWNER_WRITE
           RENAME          wpa_supplicant.conf
           )
   FILE(REMOVE ${src})
ENDMACRO(ETC_WPA_INSTALL src)
</code>

but the INSTALL doesn't actually run until `make install` (as
expected) whereas everything else does. So I get a decrypted file
which is immediately removed when I run `cmake .`! How silly of me

Is there a way to have the decryption as a dependency of install
target and have the removal at the end also?

How would you implement this?

Thanks,
Gavin

PS: Of course, I'll wrap up the gpg call in a FIND_PROGRAM for 1.0 :P
