 Use the Online Package Manager to get BGRABitmap and BGRAControls.
 
+Notice that you must check only the packages "bgrabitmappack.lpk" and "bgracontrols.lpk" in the Online Package Manager. The other packages are optional and may need third party packages / libraries to work (OpenGL and PascalScript).

 ### Optional Components
 
 Since v4.4 the components TBCDefaultThemeManager, TBCKeyboard and TBCNumericKeyboard are not installed by default to allow Linux users to get a seamless installation with the Online Package Manager not installing third party stuff. If you want these components turn on the "Register unit" in the package options for each file (bcdefaulthememanager.pas, bckeyboard.pas, bcnumerickeyboard.pas) then compile and rebuild Lazarus. On Linux you need to install libxtst-dev and libgl-dev first.
