Muchikamu chakapfuura Iyi nyaya inonakidza yakataura nezve kuronga raibhurari yemusoro mukati meCMake kuvaka system jenareta.

Panguva ino tichawedzera raibhurari yakaunganidzwa kwairi, uye zvakare kutaura nezve kubatanidza mamodule kune mumwe nemumwe.

Sekare, avo vasina kushivirira vanogona pakarepo enda kune yakagadziridzwa repository uye bata zvinhu zvose nemaoko ako.

Iye zvino tave neyakajairwa block modules, uye isu tinokwanisa kuatonga: kuanyora muchimiro chechero kuoma, kuaisa muhurongwa kana kuabatanidza pamwechete mukati memusangano mumwe chete.

Kuiswa muhurongwa

Imwe yesarudzo yekushandisa module ndeyekuisa yedu module muhurongwa.

Shandisa

Nzira dzekubatanidza dzakasiyana, asi mhedzisiro yacho yakafanana. Muzviitiko zvese izvi, zvinangwa zvichave zviripo muprojekiti uchishandisa module yedu Mylib::myfeature ΠΈ Mylib::mylib, iyo inogona kushandiswa, semuenzaniso, seizvi:
